1.1.11.1.11.1.11.1.1 IntroductionIntroductionIntroductionIntroduction totototo LinkLinkLinkLink AggregationAggregationAggregationAggregation

Link aggregation means aggregating several ports together to form an aggregation group,so as to implement outgoing/incoming load sharing among the member ports in the groupand to enhance the connection reliability.Depending on different aggregation modes, aggregation groups fall into two types: staticLACP and dynamic LACP. Depending on whether or not load sharing is implemented,aggregation groups can be load-sharing or non-load-sharing aggregation groups.

FigureFigureFigureFigure 1-11-11-11-1 Network diagram for link aggregation configuration

For the member ports in an aggregation group, their basic configuration must be the same.The basic configuration includes STP, QoS, VLAN, port attributes, and other associatedsettings.� STP configuration, including STP status (enabled or disabled), link attribute(point-to-point or not), STP priority, maximum transmission speed, loop prevention status.� QoS configuration, including traffic limiting, priority marking, default 802.1p priority,traffic monitor, traffic redirection, traffic statistics, and so on.� VLAN configuration, including permitted VLANs, and default VLAN ID, tag vlan list forhybrid port and allowed vlan list for trunk port.� Port attribute configuration, including port rate, duplex mode, and link type (Trunk,Hybrid or Access). The ports for a static aggregation group must have the same rate andlink type, and the ports for a dynamic aggregation group must have the same rate, duplexmode (full duplex) and link type.



1.1.21.1.21.1.21.1.2 IntroductionIntroductionIntroductionIntroduction totototo LACPLACPLACPLACP

The purpose of link aggregation control protocol (LACP) is to implement dynamic linkaggregation and disaggregation. This protocol is based on IEEE802.3ad and usesLACPDUs (link aggregation control protocol data units) to interact with its peer.After LACP is enabled on a port, LACP notifies the following information of the port to itspeer by sending LACPDUs: priority and MAC address of this system, priority, number andoperation key (it is so called O-Key) of the port. Upon receiving the information, the peercompares the information with the information of other ports on the peer device todetermine the ports that can be aggregated with the receiving port. In this way, the twoparties can reach an agreement in adding/removing the port to/from a dynamicaggregation group.

1.1.31.1.31.1.31.1.3 OperationOperationOperationOperation KeyKeyKeyKey (O-Key)(O-Key)(O-Key)(O-Key)

An operation key of an aggregation port is a configuration combination generated bysystem depending on the configurations of the port (rate, duplex mode, other basicconfiguration, and administrative key) when the port is aggregated.1) The ports in the same aggregation group must have the same operation key (O-Key)and administrative key (A-Key).2) The administrative key (A-Key) and operation key ( O-Key) of an LACP-enableaggregation port is equal to its aggregation group ID+1.3) The administrative key (A-Key) and operation key ( O-Key) of an LACP-enableaggregation port cannot be modified.4) The operation key (O-Key) which is contained in LACPDU of an LACP-enableaggregation port is the same as its peer.

When a static aggregation group contains only one port, you cannot remove thewhole aggregation group unless you remove the port.LACP is disabled on the member ports of static aggregation groups, and enabling LACPon such a port will not take effect.

It is manually set byusers. The dynamic aggregation group in active mode will actively send LACPDUs;group in passive mode will only response LACPDUs passively. When interconnecting withanother device, static mode can only interconnect with static mode; active mode caninterconnect with both active and passive mode, but passive mode can only interconnectwith active mode. The default mode is ACTIVE.

In dynamic aggregation group, only bundled ports cantransceive LACP protocol packets; others cannot.

Note:Note:Note:Note:

In an aggregation group, the bundled port with the minimum port numberserves as the master port of the group, and other bundled ports serve asmember ports of the group.No-bundled ports are the ports which fail to form link aggregation with otherports in the dynamic aggregation.

There is a limit on the number of bundled ports in an aggregation group. Therefore, if thenumber of the member ports that can be set as bundled ports in an aggregation groupexceeds the maximum number supported by the device, the system will negotiate with itspeer end, to determine the states of the member ports according to the port IDs of thepreferred device (that is, the device with smaller system ID). The following is thenegotiation procedure:

1) Compare device IDs (system priority + system MAC address) between the two parties.First compare the two system priorities, then the two system MAC addresses if the systempriorities are equal. The device with smaller device ID will be considered as the preferredone.

2) Compare port IDs (port priority + port number) on the preferred device. Thecomparison between two port IDs is as follows: First compare the two port priorities, then



the two port numbers if the two port priorities are equal; the port with the smallest port IDis the bundled port and the left ports are standby ports.

The device ID consists of system priority and system MAC address, that is, device ID =system priority + system MAC address.

When two device IDs are compared, the system priorities are compared first, and thesystem MAC addresses are compared when the system priorities are the same. Thedevice with smaller device ID will be considered as the preferred one.

Note:Note:Note:Note:

Changing the system priority of a device may change the preferred devicebetween the two parties, and may further change the states (bundled orstandby) of the member ports of dynamic aggregation groups.

When thenumber of members in an aggregation group exceeds the number of bundled portssupported by the device in each group, LACP determines the bundled and standby statesof the ports according to the port IDs. The ports with superior port IDs will be set tobundled state and the ports with inferior port IDs will be set to standby state.

The port ID consists of port priority and port number, that is, port ID = port priority + portnumber. When two port IDs are compared, the port priorities are compared first, and theport numbers are compared if the port priorities are the same. The port with smaller portID is considered as the preferred one.

LACP provides link redundancy mechanism to guarantee the redundancy conformity ofthe two interconnected devices and user can configure the redundant link which isrealized by system and port priority. The steps are as following:

Step 1 Selection reference. The two devices know the LACP sys-id and system MACaddress of each other through LACPDUs exchanges. The system priorities are comparedfirst, and the system MAC addresses are compared when the system priorities are thesame. The device with smaller device ID will be considered as the preferred one.

Step 2 Redundant link. The port priorities are compared first, and the port numbers arecompared if the port priorities are the same. The port with smaller port ID is considered asthe preferred one.
